so the sport package from 2011 is split in to three parts.
one part comes standard on 2012 , one part comes from 2012 sport package and other part is a option...

Sort of,
- There are more items standard, including the Driving Dynamic Control that gives user control of accelerator response characteristics, engine response, the power steering characteristics, the Dynamic Stability Control (DSC) thresholds and, on automatic models, the shift characteristics of the transmission.
I believe some of this was available with 2TB - Sport Auto Transmission, but some may have been part of 2VA - Adaptive Drive that cam with ZDH package.

For 2012, the ARS option for $2,500 includes both ARS and 2VA Adaptive Drive. Ths is the same as the 2011 ZDH package, except 223 has been moved to the Sport Package:
- 229 Active Roll Stabilization (ARS)
- 2VA Adaptive Drive

So, the full sport and adjustability options went up $1,200 for 2012 ($4,900 -> $6,100)
